ERROL R. ELDRED AND WILLIAM R. ELDRED, OF EL PORTAL, CALIFORNIA.

CRUDE-0L3 BURNER.

Application filed March 6, 1923. Serial No. 623,119.

To all whom it may concern:

Be it known that we, ERROL R. ELDRED and WILLIAM R. ELDRED, citizens of the United States, residing at El Portal, county of Mariposa, State of California, have invented certain new and useful Improvements in Crude-Oil Burners; and we do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in crude oil burners, and particularly to a type in which the oil flows by gravity.

The principal object of our invention is to provide a burner of the above general class so constructed that a very intense heat will be had with their use, and a fire of even intensity will be thrown to all points of the furnace or firebox into which the burner may be projected.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Fig. 1 is a side elevation of the burner, showing the same arranged in connection with the necessary piping.

Fig. 2 is a front end view, somewhat in perspective, of a type of the burner especially adapted for use in rectangular fireboxes.

Fig. 3 is a fragmentary section of the flame-emitting end thereof.

Fig. 4 is a front end view of a modified type of burner, suitable more especially for use in round fireboxes.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes the burner itself, hereinafter more particularly described, connected to the rear end of which is a horizontal pipe 2, terminating in a horizontal T 3, connected to the upper side of which is an oil feed pipe 4 having a control valve 5 interposed at a suitable point.

Connected to the rear end of T 3 and projecting thereinto for a certain distance beyond the connection of the pipe 4 therewith is a pipe 6, smaller in diameter than said T and pipe 2, this pipe being a. steam or atomizer pipe, and having a control valve 7 interposed therein.

The burner 1 comprises a rear sleeve 8 to receive the pipe 2, and a head 9 at the opposite end extending in a plane at right angles to said pipe and relatively long compared to its height.

The burner is of course hollow, and the head face is provided with a plurality of orifices 10 extending thereacross in suitably spaced relation.

The holes are of gradually increasing size from the center of length of said face toward the ends, as shown inFig. 2, while they are bored, especially those towards the ends of the face, on a gradually increasing slant from the longitudinal axis of the burner, in such a manner that the flame delivered from the burner will spread out fanwise. In other words, the axes of the holes lie on lines radiating from a common point a certain distance to the rear of the head, as shown in Fig. 3.

By reason of the small size of the holes at the centerof the burner and which are in line with the oil delivery and atomizer pipes, the oil which of course tends to pass out in the straight line of its flow, is choked and forced to the side of the central line, the larger sizes of the holes away from the direct line of pressure counteracting for the loss of pressure due to its sidewise deflection.

Provided of course that the holes are correctly proportioned as to size, the pressure of the fuel issuing from the holes will be the same for all, thus insuring a fire of equal intensity throughout.

In the style of burner 1 shown in Fig. 4, the head9 itself is rounded, to suit round fireboxes, the holes being radial from the center of curvature of the head.

This circular effect may of course be carried as far as suitable, or so that the burner is practically a complete cylinder, if such should be found desirable.

The oil to be burned is fed into the members 3 and 2 from the pipe 4, the'steamjet issuing from the inner end of the pipe 6 serving to atomize the oil and force the same out through the holes in the head face of the burner.

From the foregoing description it will be readily seen that We have produced such a device as substantially fullills the objects of the invention as set foi'tlr lierein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may he resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described our invention, What We claim as new and useful and desire to secure by Letters Patent is:

1. A crude oil burner comprising a hollow head adapted at its inner end for connection to a source of fuel supply, and a horizontal line of spaced holes in the outer end of the head, said holes increasing in size from a point opposite the supply connection.

2. A crude oil burner comprising a hollow head adapted at one end for connection to a source of fuel supply, and a horizontal line of spaced holes at the opposite end positioned substantially in a vertical plane, said holes increasing in size on each side of a line extended through the head centrally of the supply connection. 7

'to a supply pipe, the opposite end of the body lying in a plane substantially vertical and at rightangles to the supply pipe, and extending equally to each side of the center line oi said pipe, and a line of horizontally disposed and spaced holes in said end increasing in size on each side of said center line, and being bored at increasing angles relative theieto in a manner to cause the fuel to spread fanwise from the burner.

In testimony w iereof We allix our signatures.
